Proctor caching is technology solution used during online SOL testing that is based on the concept of storing Internet content files electronically in cache to reduce the bandwidth demand needed when accessing the Internet. Using proctor caching can greatly reduce the level of risk associated with relying on Internet connectivity and network performance while administering online SOL tests. School divisions are strongly encouraged to implement proctor caching or some other comparable cache solution during online SOL test administrations.
